In 1973, LSMB was dissolved and Tanzania Cotton Authority was established under the Cotton Industry Act No. 3 of 1973. The function of TCA was to promote the development of the cotton industry in Tanzania.

However in 1976, TCA took over the control of the entire industry from production, seed cotton buying, processing and marketing of lint after dissolution of the Regional Co-operative Unions (RCU’s).

The government reinstated the Regional Co-operative Unions in 1984 after repealing the Cotton Industry Act No. 3 of 1973 and Tanzania Cotton Marketing Board was formed in place of Tanzania Cotton Authority. TCMB was established by the Tanzania Cotton Marketing Board Act No. 19 of 1984 to carry out the marketing of cotton lint and cotton seeds.

However, the Principle act i.e. TCMB Act No. 19 of 1984 was amended by deleting all references to the name TCMB and substituted them by Tanzania Cotton Lint & Seed Board whose functions were mainly to regulate and control the quality and marketing of cotton lint and seed cotton.

However, the Act that formed TCLSB did not address production related problems facing the industry. This necessitated the formation of Tanzania Cotton Board (TCB) by the Act of Parliament i.e. Cotton industry Act No. 2 of 2001 which name came into effect on July 2004.
